### ⭐ No magic here
*by O***D on June 6, 2022*

Does not work in water at all.

### ⭐⭐⭐⭐⭐ works great underwater
*by B***N on December 11, 2018*

I tried several adhesives and this is the first one that seems to work. I like it because you can apply underwater and it holds. We have black tile in our spa and fountain so this is perfect & hard to find.
